The name used to describe a prevention strategy in which all blood and potentially infectious materials are treated as if they are, in fact, infectious, regardless of the perceived status of the source individual. In other words, wether or not you think blood/body fluid is infected with blood borne pathogens, you treat it as if it is.
This approach is used in all situations where exposure to blood or potentially infectious materials is possible. This also means that certain engineering and work practice controls shall alsy be utilized in situations where exposure may occur
Vacutainer is a federally and internationally registered trademark owned by BD (Becton, Dickinson and Company) that is used in connection with a complete system of tubes, needles and needle holders, sharps collectors and safety devices in blood collection.
The Vacutainer evacuated tube, for example, automatically aspirates the correct aount of blood into a tube. It is used indtead of a syringe. Despite the fact that BD owns the Vacutainer trademark, the term has become so widley used to describe similar blood collection tubes and devices, that it has become a generically used term

The needed is used to attach to a Vacutainer holder. The needle has a male thread on one end which screws into the holder. The threaded end also has a large guage needle, enclised by a rubber sheath. This needle will puncture the stopper of a Vacutainer tube allsoing blodd to enter the tube. Upon withdrawal of this needle from the tube, the rubber sheath covers the needle bevel, stopping the flow of blood. Thus, any number of tubes may be drawn with ony one single venipuncture
